Air Conditioning Repair in Chiswick
One call covers air conditioning repair in Chiswick, from the first look to sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Air conditioning running but not cooling
- A suspected refrigerant leak
- A noisy indoor or outdoor unit
What the work involves, system by system
Condensate drains and pumps
We clear the drain, test the pump and check the fall until the condensate runs away properly. If a pump has failed, we replace it and test it before we leave.
Wall-mounted split systems
On a wall-mounted split, the indoor and outdoor units talk to each other through a control cable. A break in that communication usually brings up an error code and testing finds whether it’s the cable, a board or a connection.
How we handle air conditioning repair in Chiswick
Not sure whether it’s worth calling an engineer? A quick check of the filter, settings and remote can rule out the simple causes, then call us on 07833 053749 or fill in the contact form if the problem is still there. We reply to enquiries the same working day. The work covers multi-split systems, wall-mounted split systems and heat pumps, and the jobs we see most are a noisy indoor or outdoor unit and a unit that has lost refrigerant.
In a London area like Chiswick, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

When to call us in Chiswick
Refrigerant leaks often start at joints: joints, valves and sections of pipe worn by vibration or damage. Corrosion on coils can also cause leaks over time and many leaks are slow enough to go unnoticed for a while.
Customers typically contact us when they notice one of these:
- A fault code on the display
- A system that runs but does not cool the room
- A system that will not switch on
Shops and offices around Chiswick station often cannot wait for cooling to come back, which is what the 24/7 line is for.
What your quote should include
- What the manufacturer’s warranty covers and for how long
- Proof of F-Gas company certification
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
What air conditioning will not do
Before booking, it helps to know what’s not included:
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- An old system with obsolete parts
- A leak on an old R22 system
If in doubt, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll say what we think.

Advice
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
